ArticleItem Open Access CONCURRENT THEILERIOSTS AND ANAPLASMOSIS INFECTION IN CROSSBRED COWS - A CASE REPORT(TANUVAS, 2003-06) Sundaram, A. Meenakshi; Sivaseelan, S.; Ramamurthy, N.; Sundaraman, M.N.; TANUVASGenus Theileria, the intracellular parasite and Gcnus Anaplasma, the intraccllular rickettsia cause the diseases Theileriosis a.nd Anaplasmosis respectively in animals. They are transmitted by ticks and affect a wide range of domestic and Wild animals. Annplasma marginale chiefly affects cattle and causes mortality as high as 80 per cent (Soulsby,1968). Reports on concurrent infection of anaplasmosis and theileriosis in cattle are very scarce.ArticlesItem Open Access Evaluation Of Pre-Freeze And Post-Thaw Sperm Motion Characteristics Of Goat Spermatozoa By Computer-Assisted Semen Analysis(TANUVAS ; Chennai, 2005) Sundaraman, M.N.; Edwin, M. John; TANUVASArticleItem Open Access EVALUATION OF PRE-FREEZE AND POST-THAW SPERM MOTION CHARACTERISTICS OF GOAT SPERMATOZOA BY COMPUTER-ASSISTED SEMEN ANALYSIS(Indian Society for Sheep and Goat Production and Utilization, 2005-04) Sundaraman, M.N.; Dewin, M. John; TANUVASConventionally, sperm mortality assessment is carried out on phase contrast microscope by visual approximation of proportion of progressively moving spermatozoa, which however does not eliminate the human error/bias. In recent years, rapid development has taken place in designing sophisticated equipment and procedures for semen evaluation. The use of computer assisted semen analysis (CASA) has given a new dimension to evaluation of quality of spermatozoa (Amann and Hammerstedt 1980; Tuli et al., 1992; Tardiff et al., 1998). Besides assessment of motility, CASA facilitates evaluation of sperm motion and morphological characteristics, which would not otherwise be possible by conventional methods. Therefore, a study was undertaken to assess the effect of cryopreservation on the sperm characteristics of goat spermatozoa by CASA technique.
